BLACKING-MACI-IINE.

Specification of Letters Patent.

Patented May '7, 1912.

Application filed December 31, 1910. Serial No. 600,263.

ferred to generically as blacking, to the heels or soles of boots andshoes. For convenience, the work will hereinafter be referred to as theheel, it being understood that except as obviously required by thecontext, the term is used in a broad sense to designate the heel, soleor other part of the shoe being treated.

The general objects of the invention are to provide a heel blackingmachine with the d of which the edge of the heel and preferably also theexposed surfaces of the rand may be thoroughly blacked withoutspattering or smearing blacking upon the other parts of the shoe; whichshall perform its operations rapidly and uniformly; which shall becapable of handling a wide range of work without change or adjustment ofthe parts, and which generally shall be an improvement on the machinesof this character heretofore pro-posed.

With these ends in view and with reference particularly to the thoroughcoating of the heel edge and rand with blacking, an

important feature of this invention consists in the provision of drivenmeans for applying blacking to the heel edge and independently drivenmeans for applying blacking to the rand crease.

In the preferred embodiment of the invention the blacking is applied tothe heel edge by means of a rotary brush, and a device, hereinafterdesignated the rand guide, operates simultaneously therewith to applyblacking to the rand crease. This device performs the functions both ofa rand crease guide and a rand blacking devlce,

having one face that runs in contact with the counter of the shoe andanother face that runs in contact with the'upper exposed surface of therand, the latter face being supplied with blacking. The face thatengages the counter is kept clean by means of scrapers of novelconstruction.

In machines of this class that have been proposed heretofore, theblacking applying brushes have, so far as I am aware, been constructedto wipe blacking along the heel edge in a direction parallel to the toplift. These constructions have required various adjustments or changesof parts to accommodate different styles and heights of heels.

In the preferred embodiment of this invention, however, a guiding meansis arranged to position the shoe to the blacking applying brush so thatthe brush will wipe across the heel preferably fro-m the rand crease tothe tread face. This machine, therefore, will accommodate withoutadjustment a great variety of styles and heights of heels, the brushbeing sufficiently flexible to fit into the curves of heels differingwidely in shape. I regard this as an important feature of my invention.

In the illustrated construction, the applying brush is arranged torevolve in a substantially horizontal plane while the rand. crease guiderevolves in a substantially vertical plane. I prefer to form the guideconcave in shape and locate it so that it encircles part of the brushand has its guiding edge running in contact with the periphery of thebrush at the forward portion of the latter. This arrangement enables meto feed blacking to the brush in a novel man-' ner, consisting inconveying it to that face of the guide that runs in contact with therand, from which face the brush picks it up.

A further important feature of this invention consists in providingnovel means for removing the surplus blacking from the applying brushand for straightening out the bristles of the same. For applyingblacking to the heel edge, I prefer to use a brush having soft bristles,since such a brush fits better into the curves of different styles andheights of heels than does a stiffer bristled brush. WVhen such a brushbecomes loaded with blacking, however, the bristles tend to pack or matdown, and for the purpose of straightening up the bristlesand at thesame time maintaining a uniform quantity of blacking on the brush, I usea rotary stiff bristled brush arranged to run in peripheral contact withthe applying brush and at a greater speed than the applying brush. Thisstiff bristled brush takes the blacking from the applying brush andbecause of its greater speed it picks up the bristles of the soft brushand straightens them out. The blacking is then removed from the stiffbristled brush by a stationary scraper preferably held in yieldingcontact with the periphery of this brush.

The invention is directed also to the provision of adjustments tocompensate for wear, a novel receptacle for holding the brush. to keepit from drying out when not in use, an adjustable edge rest, and tovarious other features including certain details of construction andarrangements of parts that will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a view in front elevation of aheel blacking machine embodying this invention; Fig. 2 is a plan view ofthe same; Fig. 3 is a perspective view of the machine with certain partsbroken away; Fig. 4 is a front elevation of the scraper device; Fig. 5is a front elevation of a modified form of the invention; Fig. 6 is asectional view showing a detail of the construction of the machine shownin Fig. 5; and Fig. 7 is a fragmentary view in front elevation of therand guide.

The frame of the machine comprises a post 2 and a head l generallyrectangular in shape and having suitable bearings for a main shaft Thisshaft has loosely mounted thereon a pulley 8 that may be thrown into orout of driving connection with the shaft by means of a clutch 10 havingan operating handle 12. Fast on the driving shaft 6 near its forward endis a worm gear 14; that rnesheswith and drives a gear wheel 16 securedfast to a bushing 17 on to which also the edge blacking brush 18 isclamped by a nut 19. This bushing with the gear and brush revolves on avertical spindle 20 that is removably held in operative position in theframe by a spring pressed pin 21 arranged to slide through a hole in theframe into a groove formed in the spindle 20 near its upper end, as bestshown in Fig. 3. A hole is drilled into the spindle from the bottom .ofthe groove into which the pin can slide and hold the spindle againstrotation. The spindle 20 is mounted in a portion 22 of the frame that isadjustable on the frame head. in a direction parallel with the shaft (3.A bolt 23 threaded into the frame and projecting through a slot in thepart 22 serves to hold this part in adjusted position. The

shaft 6 has fast thereon another worm gear 24 that meshes with a gearwheel 26 fixed on a shaft 28 lying at right angles to and sup portedbelow the shaft 6. This shaft carries a large blacking conveying disk 30that normally dips into a body of blacking held in the tank 32. In Fig.3 the tank is shown in its lowered or inoperative position, but itnormally occupies the position in which it is shown in Fig. 1, in whichposition it is held by a set screw 33.

Supported substantially parallel to the shaft 28 but inclined slightlyto the horizontal is a shaft 34: that carries the rand guiding andblacking device 36. This shaft is rotatably mounted in a bushing 38 thatis slightly adjustable axially in the frame and is held in adjustedposition by a set screw 40. The shaft 34 is driven by means of gears4-1, 42, 43 connecting it with the shaft 28.

The rand guide 36 preferably is deeply concave or bowl shaped as shownin the drawings and is so positioned with reference to the brush 18 thatit encircles a segment of the brush and at its forward edge runs incontact with the periphery of the same. A lip of appropriate shape torun in the rand crease 1s formed at the edge of the rand guide.

When power is applied to the machine the brush 18, rand guide 36 anddisk 30 will be rotated in the directions indicated by the arrows inFig. 3. The rand guide is ad justed so that its rand engaging face runsvery close to the face of the disk 30 as indicated in the drawings. Asthe disk lifts blacking from the tank 32 it is taken off by the randengaging face of the guide 36 and since the brush 18 wipes across thisface of the guide it receives its supply of blacking therefrom. The randguide is inclined some what to the disk 30 as shown so that its edgecomes in contact with the blacking on the disk only at one point. Theadjustability of the bushing 38 in the frame affords a means for varyingthe position of the rand guide relative to the disk and consequently onemeans for regulating the quantity of blacking taken up by the randguide. A. further means for regulating the supply of blacking isafforded by a scraper consisting of a screw threaded bolt a l receivedin a threaded hole formed in the tank 32 and having a spring" in Figs.1, 2 and 3 comprises a bracket 48 I move any blacking that may becomedried on' the rand guide. The weight of this scraper usually issuflicient to cause it to operate effectively. The other scraperpreferably is pressed against the rand guide and for this purpose thecasing carries a rod 56 that is bent at its upper end to overlie thescraper 54 and a spring 58 interposed between the part 54 and the bentend of the rod applies the necessary pressure to the scraper. The tank32 carries adjustably an edge rest 60 and a thumb screw 62 by which therest may be secured in adjusted position.

In using the machine the workman rests the edge of the heel against thedevice 60 and presents the shoe to the members 18 and 36 so that the lipof the rand guide is inserted in the rand crease. The face of the guide36 that engages the rand is the face that receives the blacking from thedisk 30 and as this guide revolves it deposits blacking on the upperexposed surface of the rand. At the same time the brush 18 wipesblacking across the heel from the rand crease to the top lift. Theworkman usually starts with the toe of the shoe held upward so that thepart of the heel edge near one breast corner is blacked first. He thenswings the shoe downward while keeping the lip of the guide in the randcrease thus causing the entire heel edge from one breast corner aroundthe end to the other breast corner to pass in contact with the brush andtherefore to be blacked.

The brush 18 preferably has soft bristles to enable it to fit betterinto the curves of heels of the more exaggerated shapes. The bristles ofsuch a brush are packed down by the work and being heavily loaded withblacking are not able of their own resiliency to straighten out. For thepurpose of maintaining the brush in proper operative con dition and forthefurther purpose of removing the surplus blacking therefrom there ispositioned beside the brush 18 and running in peripheral contacttherewith a stiff bristled brush 64. This brush is carried on a verticalspindle 66 rotatably mounted in the frame piece 22 and the spindle isdriven by a gear 68 thereon meshing with a gear 70 on the main shaft 6.The ratio of these gears is such as compared with the ratio of the gears14 and 16 that the brush 64 is driven at a much greater speed than thebrush 18. Since the brushes revolve in opposite directions, the effectof the brush 64 when it engages the brush 18 is to sweep forward thebristles of the latter and to straighten them out. At the same time, thebrush 64 picks off the surplus blacking from the applying brush 18 thusmaintaining a uniform supply on the applying brush.

It is necessary to remove the blacking from the brush 64 and for thispurpose I have provided a stationary scraper comprising a sheet metalapron 72 preferably of greater height than the brush 64 and curved to aC-shape in cross section. The apron is secured at one edge to an uprightstem or rod 74 held loosely in a socket o-rbearing formed in the framepiece 22. The opposite edge of the apron bears against the periphery ofthe brush 64 so that its open or concave side is toward the brush. Inorder to press the edge of the apron against the brush a weight 7 6 ismounted on the top of the stem 74 and an inclined cam face is formed onthe upper edge of the stem bearing against which face a screw 80'threaded into the stem bears. It will be clear from an inspection ofFig. 4 that the effect of this arrangement is to impart to the stem 74 aconstant tendency to turn on its axis in a direction to press the edgeof the apron against the brush 64. The bristles of this brush thereforewhen they come in contact with the edge of the apron are bent therebyand as they leave the edge they straighten out with a snap that throwsoff the blacking. The concave surface of the apron is in the path of theblacking so thrown and serves to collect it. The tank 32 has anextension at its forward right hand corner, as seen in the drawings,over which the apron 72 and brush 64 are located, and the blackingcollected by the apron therefore drips into this portion of the tank. Inorder to avoid all possibility of the brush 64 throwing blacking on tothe workman, the extension of the tank is provided with a shield 82 thatpartly incloses the brush.

If the brush 18 is allowed to stand idle for any great length of time,as for instance, over night, the blacking that it holds will be driedout and the brush thus will be rendered unfit for use until it has beensoftened up again. To obviate this difliculty I have provided themachine with a receptacle in which the brush maybe placed and kept moistwhen not in use. This receptacle comprises a water tight basin 84 moldedon to the top of the frame head 4 and a tall cover 86 therefor. Thebasin has a spider 88 attached to its bottom to support the lower end ofthe bush ing 17 on which the brush 18 is mounted. l/Vhen the machine isto remain idle for several hours, the workman retracts the pin 21 thatnormally holds the brush in. operative position, then removes the brush18,

&

bushing 17, gear 16 and spindle 20 as a unit, places them in an uprightposition in the basin 84 and covers them with the device 86. The basinis designed to be kept partially filled with water to keep the air inthe receptacle moist and thus keep the brush from drying out. The spider88 is of such height relatively to the walls of the basin that even whenthe basin is filled with water the brush cannot come in contact with theWater.

In Figs. 5, 6'and 7 I have shown a machine of the same generalorganization as that above described but differing therefrom in certaindetails. In this machine the rand guide 36 is supported on a horizontalshaft and the guide lies substantially parallel with the disk 30. Therand engaging face of this guide is beveled as shown in Fig. 6 and hasshallow pockets 90 formed in said beveled face. The shaft 34 on whichthe guide is mounted is geared to the shaft supporting the disk 30 as inthe machine previously described, but in this machine the shaft 34 isrevolved in a direction opposite to the direction of rotation of thedisk 30'. Then the machine is running, a small quantity of blackingremains constantly at the point where the guide 36 leaves the disk 30and this blacking is picked up by the rand engaging face of the guide 36and the pockets 90 formed therein.

The downward movement of the rand guide at the point where it engagesthe brush 18 tends to bend down the bristles at the lower portion of thebrush and in order to counteract this action, I have secured to thespindle 20 below the brush one end of a Hat metal strip 92. This stripis bent sharply at about its middle and its free end is turnedbackwardly to present an inclined face to the lower side of the brush.

It will be clear from an inspection of Fig.

.5 that as the brush 18 revolves the bristles at its lower side willride up over the inclined portion of the strip 92 and will be pressed upto the main body of the brush. The bristles on the lower side of thebrush are supported also by a collar 93, shown in Figs. 1 and 5, whichpreferably is integral with the nut 19. The machine shown in Fig. 5 alsoincludes a modified scraping device for operating on the rand guide 36.According to this arrangement the bracket that supports the shaft 34carries two pins 94 extending substantially parallel with the shaft andpositioned one above and one below the shaft. The scraper comprises asemi-circular yoke having at each end a holder 96 that is recessed toreceive one of the pins 94. Springs 98 are interposed between the endsof the pins and the bottoms of the recesses and operate to press, theholders 96 toward the surface of the rand guide 36. Each of the holdersis slotted to re ceive a piece of felt, cork, leather or similarmaterial to bear against the rand guide and scrape off any blacking thatmay adhere to its outer surface. This arrangement affords the advantageof subjecting opposite sides of the rand guide to the same pressures,thereby avoiding any tendency to crowd the shaft 34 against one side orthe other of its bearing. The thrust of the scrapers on the rand guideis resisted by a collar 100 secured on the end of the shaft 34.

The edge rest shown in Fig. 5 is provide'd with a split stem that may beinserted in any one of a plurality of holes drilled through a bossformed on the forward end of the tank 32. The tank in this construc tionis supported by a pin 102 which extends through both standards .of theframe head, the pin being shouldered where it passes through one or bothof these standards so that it can not be displaced accidentally.

An important advantage of the construction disclosed in this applicationis that the brush 18 will fit any heel from a spring heel or the styleused on a mans heavy shoe to the French heels of womens shoes. Noadjustment, except possibly that 'of the edge rest, is necessary inorder to treat different sizes and styles of heels. Consequently, whenthe machine has been installed and once adjusted it is always ready forany kind of work and need be adjusted only to compensate for wear.
